Nomenclature and distribution of the of the porcupinefi sh family Diodontidae (Pisces, Teleostei)

JEFFREY M. LEIS

Ichthyology, Australian Museum, 6 College St, Sydney, NSW 2010, Australia (e-mail: jeffl @austmus.gov.au) Abstract Leis, J.M. 2006. Nomenclature and distribution of the species of the porcupinefi sh family Diodontidae (Pisces, Teleostei). Memoirs of Museum Victoria 63(1): 77–90. The tetraodontiform fi sh family Diodontidae is widely distributed in tropical and temperate marine waters. The family has more than 70 nominal species, over 60% of which were described in the 100 years following Linnaeus. As a consequence, many descriptions are less than detailed, and many types are no longer extant, if they existed at all. The high incidence of synonymy, the many ʻoldʼ descriptions and the wide geographical distributions of the species has led to a great deal of confusion. The present study, based on examination of diodontid holdings in 29 major collections, and including the extant types of all but two of the nominal species, attempts to clarify the nomenclature and distribution of the species of the family. Although some species boundaries are not entirely clear, only 18 or 19 of the nominal species are herein regarded as valid (one as a subspecies). Tentative assignments of species to genera maintain current usage. Final assignments to genera must await a cladistic analysis of relationships within the family. Four species are circumtropical, four species (plus a subspecies) are confi ned to the Atlantic and appear to form a species group, four species are widely distributed in the tropical Indo-Pacifi c, two species are confi ned to tropical Australasia, and three are endemic to temperate Australia. One species described from New Zealand either occurs also in Australia, or is a synonym of an Australian species. Synonymies, a key to the recognized species and a table of the identities of nominal species are provided.

Introduction This paper lists the senior synonym of each morphologically- defi ned species, followed by the junior synonyms. Brief The porcupinefi sh family Diodontidae contains about justifi cations for synonymies are provided, as are descriptions 19 species in seven or eight genera of warm to temperate seas. of the distribution of the species based on material examined There are about 75 nominal species in the family, and several or on identifi able literature records. In addition to the key of the species have very wide distributions. The species are provided here, regional keys to the species, and illustrations of conspicuous, readily captured, of unusual morphology, and them, can be found in Leis (1986, ref. 5686 – western Indian have been the focus of interest by naturalists from ancient Ocean); Leis (2001, ref. 26318 – western central Pacifi c Ocean: times. Several species have pelagic stages that reach large this key also covers all species in the eastern Indian Ocean); sizes and differ in appearance from the demersal adults. Allen and Robertson (1994, ref. 22193 – eastern Pacifi c Ocean); All this has led to a great deal of confusion as to the number Leis (2003, ref. 27121 – western central Atlantic Ocean); Leis of species, their distributions and the correct names for (in press, eastern central Atlantic Ocean). The key in Leis them. The purpose of this paper is to clarify a number of (2001, ref. 26318) includes all Indo-Pacifi c species and genera nomenclatural issues and the distributions of the species. recognized herein, except the two temperate Australasian Due to their wide distributions, the species are obvious targets species Diodon nicthemerus Cuvier and Allomycterus pilatus for molecular genetic studies, and it is reasonable to expect Whitley (for these, see Kuiter, 1993, ref. 23929, or Gomon et that some taxa that are currently, on the basis of morphology al., 1994, ref. 22532 ). alone, considered to represent a single, widespread species will be subdivided once genetic studies are undertaken. Materials and methods Conversely, some Atlantic taxa have less than clear separations and may eventually be considered conspecifi c. Therefore, Abbreviations of fi ns are as follows: D, dorsal; A, anal; P, it is important to lay some groundwork for these expected pectoral; C, caudal. The spines mentioned are the dermal spines future studies. (i.e., modifi ed scales): fi ns of diodontids lack spines. These 78 Jeffrey M Leis dermal spines have subdermal bases (or roots) that have either Pacifi c genera, three of which are confi ned to Australasia, two approximately opposing bases upon which the exposed contain species that have a mixture of fi xed and erectile spines spine pivots when it elevates, or three (occasionally four) – Allomycterus, Dicotylichthys, Lophodiodon and Tragulichthys broadly more or less equidistantly spaced bases that render the – are usually recognized (see Gomon, 1994, ref. 22532 ; Leis, exposed spine immobile. The exposed portion of the spine 2001, ref. 26318) and are in this paper. Chilomycterus sensu lato varies in length and shape, but erectile spines are generally (about ten species with nearly all dermal spines fi xed and round in cross-section, whereas fi xed spines can vary from immovable) has been more problematical. Tyler (1980, ref. round to compressed in cross-section. See Leis (1978, ref. 5529; 4477) recognized three groupings of Chilomycterus: 1) ʻAtlantic 1986, ref. 5686; or 2001, ref. 26318) for more information on Chilomycterusʼ (fi ve species confi ned to the Atlantic, and called spine morphology. Behind the massive beak-like jaws of by him antennatus, antillarum, mauretanicus, schoepfi i and diodontids is a grinding, or trituration, plate formed by the spinosus); 2) what I call herein ʻCircumtropical Chilomycterusʼ fused premaxillae and dentaries. This plate is often armed with (a circumtropical group considered by Tyler to consist of four transverse plates of teeth, called trituration teeth. species called by him affi nis, atinga, reticulatus and tigrinus); Specifi c information on types is included only if it and 3) ʻIndo-Pacifi c Chilomycterusʼ (considered by Tyler to supplements or corrects information in Eschmeyer (2005; 17 consist only of orbicularis). I agree with Tyler (1980, ref. 4477) Oct 2005 version). To keep the literature cited list to a manageable that nominal species in each of these three groups are length, it includes only references not included in Eschmeyerʼs morphologically more similar to each other than they are to (2005) on-line database (http://www.calacademy.org/research/ species in the other groups. The type species of Chilomycterus ichthyology/catalog/fi shcatmain.asp). The Eschmeyer reference is Diodon reticulatus Linnaeus (1758, ref. 2787); thus, if these number is included with the text citation. Information on Diodon groupings prove to be valid at the generic level, the circumtropical is included in Leis (1978, ref. 5529) and in Leis and Bauchot group becomes Chilomycterus, and I use it in that sense herein. (1984, ref. 12539). For Diodon, only information on species Cyclichthys typically is used for several Indo-Pacifi c species described since 1978 and information updating species (including two not mentioned by Tyler [1980, ref. 4477]), and distributions is included here. the type of Cyclichthys is the Indo-Pacifi c orbicularis; thus, the I examined specimens of diodontids from the following Indo-Pacifi c grouping can be considered Cyclichthys for the institutions (codes after Leviton et al., 1985, ref. 9683): AMS, purposes of this paper. The Atlantic group of species, regarded ANSP (loans based on holdings list), BMNH, BPBM, CAS, by Tyler to be the most phylogenetically basal, is nearly always CSIRO, FAKU, FMNH (loans based on holdings list), FRSKU, included in Chilomycterus. If these Atlantic species were LACM, MCZ, MNHN, NMNZ, NMV, NSMT, NTM, QM, removed from Chilomycterus, the generic name available for RMNH, ROM, RUSI, SAMA, SIO, SMF, UA, USNM, WAM, them is Lyosphaera, based on the unique pelagic stage found in ZMA, ZMB, ZMUC. Distributions are based primarily on at least some members of this group. Unfortunately, the identity museum specimens examined, but are supplemented with of the type species is not clear (on the basis of distribution, reliable literature accounts. schoepfi i seems most likely). Lyosphaera has not been used as a generic name for these fi ve Atlantic species, and until a full Results cladistic analysis is performed on the group, its use is not recommended. For the purposes of this paper, I use Tylerʼs term, Family Diodontidae “Atlantic Chilomycterus”, to identify this grouping. Diagnosis.

The latter was based on a specimen Kaup (1855, ref. 2571) asserted the specimen was from New from Brazil – no longer extant – that is clearly identifi able as the Guinea, but according to Günther (1870, ref. 1995) the locality Atlantic Diodon spinosus Linnaeus (see below). Le Danois of the specimen “was never known at the British Museum”. A (1959, ref. 12003) considered atringa Linnaeus to be single species (see below). approximately equivalent to Tylerʼs “Atlantic Chilomycterus” group (which includes D. spinosus Linnaeus) with several Chilomycterus reticulatus (Linnaeus, 1758) subspecies roughly equivalent to Tylerʼs species. In contrast, D. reticulatus Linnaeus (1758, ref 2787) is readily Diodon reticulatus Linnaeus, 1758: 334 (India) Diodon echinatus? Linnaeus, 1758: 335 (India) identifi able.

Some authors, different nominal species or among geographic locations. There apparently following Jordan and Evermann (1898, ref. 2444, is variation in colour pattern similar to that found in the have considered reticulatus to be a junior synonym of atringa, circumtropical Diodon holocanthus (see Leis, 1978, ref. 5529) but none have attempted to justify this view. It is clear from but, like that species, it is not obviously geographically based. Jordan and Evermannʼs description and key that they incorporated Spotting on the body is variable, although usually present to more than one species in their concept of C. atringa, including at some degree, but smaller spots are present on at least some, and least C. reticulatus and C. antennatus. Jordan and Evermann usually all, of the fi ns. The pelagic juvenile phase has a distinctly (1898) described C. atinga as having dark dorsal blotches and a different colour phase from the benthic adult. The species ʻsupraocular cirrusʼ, both features that are lacking in C. reticulatus remains pelagic to about 200 mm SL, thus providing ample (Linnaeus) and in Tylerʼs ʻcircumtropical Chilomycterusʼ, but opportunity for dispersal and maintenance of genetic continuity. present in species of the ʻAtlantic Chilomycterusʼ group. Therefore, I regard Tylerʼs group of ʻcircumglobal Chilomycterusʼ There is a great deal of confusion in the literature as to just to consist of a single species. The rationale for calling this what constitutes C. reticulatus and C. atringa. For much of the species Chilomycterus reticulatus (Linnaeus) follows. 19th century, most authors accepted Blochʼs (1785, ref. 21381) Diodon atringa Linnaeus (1758, ref. 2787) is frequently concept of D. atinga (=D. hystrix Linnaeus, 1758, ref. 2787), regarded as a synonym (often the senior synonym) of this and although Brisout de Barneville (1846, ref. 296) pointed species. This name is often misspelled atinga by authors. This is out that this was in error, the use of D. atinga sensu Bloch clearly incorrect: Linnaeus used the spelling atringa in both his persisted for some years. Séret and Opic (1981) stated without tenth and twelfth editions. Nelson et al. (2004, ref. 27807) reasons that reticulatus was a synonym of C. atringa recently explained why atringa is correct; and Eschmeyer (2005) (Linnaeus), but their illustration of C. atringa shows what used atringa. To avoid confusion with D. atinga Bloch (1785, appears to be C. antennatus (Cuvier) (Séret and Opic kindly ref. 4866), a synonym of D. hystrix, I herein use the spelling provided unpublished dorsal and lateral views of the specimen atringa for the Linnaean species, regardless of the spelling used that strengthen this opinion). Similarly, Tortonese (1973, ref. by any subsequent author. Unfortunately, D. atringa Linnaeus is 7192), without comment, listed reticulatus as a junior synonym not identifi able. There is no type, and Linnaeusʼ description of atringa, but, later, Tortonese (in Whitehead et al., 1986, ref. could apply to any of several species of Chilomycterus or 13677) illustrated as C. atringa a specimen of the eastern Cyclichthys (including C. reticulatus, C. antennatus or C. Atlantic C. spinosus mauretanicus (Le Danois), but with spinosus), and the same is true of Artedi (1738), the only source spotted fi ns, a feature I have not observed in the latter species. cited by Linnaeus, and the pre-Linnaean authors cited by Artedi. Smith-Vaniz et al., 1999 (ref. 25013) listed C. atringa Artedi, 1738 mentioned that the fi ns of his “Ostracion bidens (Linnaeus) as occurring in Bermuda, but had seen no sphaericus…”, upon which Linnaeus based his D. atringa, were specimens, stating that their listing was based on Goodeʼs spotted, but large individuals of C. antennatus (Cuvier, 1816, (1876, ref. 1832; 1877, ref. 13360) and Güntherʼs (1870, ref. ref. 993 ) also have spotted fi ns (see below), so this is not 1995) records of C. reticulatus. Unfortunately, this leads to diagnostic, as is often assumed. Linnaeus (1766, ref. 2786) cited ambiguity because, Smith-Vaniz et al. (1999, ref. 25013) could a plate in Seba (1759, ref. 18716) that represents either C. be interpreted as considering reticulatus a synonym of atinga, reticulatus or C. antennatus. Brisout de Barneville (1846, ref. or as considering that the other authors misidentifi ed their Species of porcupinefish 81

specimens. Some other workers (e.g., Fowler, 1936, ref. 6546; USNM 43860 is in fact the holotype, in spite of Eigenmannʼs Lozano Rey, 1952) have included reticulatus of authors in statement in the original 1891 description that “I did not obtain their synonymies of atringa, but not reticulatus Linnaeus it”. The holotype is in the pelagic colour phase of C. (1758, ref 2787), implying that they questioned othersʼ concept reticulatus. of reticulatus rather than that they considered reticulatus Euchilomycterus quadradicatus Waite (1900, ref. 4558) Linnaeus to be a junior synonym of atringa. from Lord Howe I. was based on a dried specimen – apparently In more recent years, a view has developed among some a beach wash-up – subsequently preserved in ethanol and in American workers that Atlantic individuals of this taxon are poor condition. Although not fi gured by Waite, Whitley (1952) C. atringa, whereas the Indo-Pacifi c individuals are either C. illustrated the holotype (with some artistic license) clearly affi nis (Robins et al., 1991, ref. 14237) or C. reticulatus (Nelson showing the caudal-peduncle spine and four-rooted spines on et al., 2004, ref. 27807), but, again, no justifi cation for this or the head that in combination are diagnostic of Chilomycterus means of distinguishing the two nominal species has ever been reticulatus. presented. Tyler (1980, ref. 4477) tentatively recognized four Chilomycterus lissogenys Günther (1910, ref. 14460) was species in this complex that have, based on his material based on an illustration by Garrett of a Hawaiian fi sh. Although examined and text, different distributions: C. atringa (western Garrett omitted some of the spines on the side of the head, he Atlantic); C. reticulatus (eastern Atlantic and Indo-Pacifi c); C. clearly showed the spine on the caudal peduncle that is tigrinus (western Indian Ocean); and C. affi nis (Eastern characteristic of C. reticulatus. The illustration showed relatively Pacifi c). However, Tyler (1980, ref. 4477) said that C. tigrinus few spots on the body, but heavily spotted fi ns, a condition well may be the young of C. reticulatus (I agree). So confusion within the range of colour variation in this species. about the identity and distribution of these species continues. The description and photo of Chilomycterus galapagosensis In summary, D. atringa Linnaeus is unidentifi able, and the Klausewitz (1958, ref. 12080) are clearly that of C. reticulatus. post-Linnaean use of the name by various authors has been The description of the nostrils alone is diagnostic. Klausewitz inconsistent as to what species was being included: at least distinguished his new species from C. atringa, which he four species and two multi-species groups have been identifi ed described as having a supraorbital cirrus and large dorsal as D. atringa by various authors at various times. In spite of blotches (presumably based on the description of Jordan and the use of C. atringa (usually spelled atinga) by several Evermann [1898, ref. 2244], which was based on more than authors, the name should be regarded as a nomen dubium, and one species), by its lack of these two characteristics. He not used. Diodon reticulatus Linnaeus is clearly identifi able, distinguished it from C. californiensis by colour, but the latter and the use of the name has been remarkably consistent: it is in pelagic-phase colour, whereas C. galapagosensis has should be used for this species. typical, spotted demersal colour. Diodon echinatus Linnaeus (1758, ref 2787) is seemingly equivalent to his Chilomycterus reticulatus (see Leis and Distribution. Circumglobal in warm temperate to tropical waters: Randall, 1982). Linnaeusʼ (1758, ref 2787) description and the W Atlantic – 39oN to 24oS Marcgrave plate to which Artedi (1738) referred could apply to E Atlantic – Madeira (and possibly to Portugal) and Cape any Chilomycterus or Cyclichthys species.

Verreaux held in MNHN) is brief, but fortunately the types of The type species of this genus is A. jaculiferus (non- A. diversispinus Bleeker are extant (see below), thus clearly Cuvier) McCulloch. McCulloch (1921, ref. 2945), apparently showing that Atopomycterus is a synonym of Dicotylichthys. following Güntherʼs (1870, ref. 1995) concept of jaculiferus, provided an excellent illustration of the species he was Dicotylichthys punctulatus Kaup, 1855 proposing as the type of his new genus. However, it was not D. jaculiferus of Cuvier (1818, ref. 18059). Whitley (1931, ref.

Confusion over the specifi c name of this species see Leis and Bauchot, 1984, ref. 12539). is dealt with under the genus. There seem to be two forms of Dicotylichthys myersi Ogilby (1910 ref. 3288) was said by this species, one with long, blade-like spines (A. whitleyi Ogilby to differ from D. punctulatus by the relative size of the form), and another with short, compressed spines.

Therefore, there may be two species of Kaup (1855, ref. 2571) reported that his type specimens came Allomycterus, and a genetic study would be useful in clarifying from the Cape of Good Hope and Mauritius. Subsequently, the situation. In addition, Kuiter (1993, ref. 23929) illustrates Günther (1870, ref. 1995) reported that the only specimen in two colour morphs among south-eastern Australian specimens BMNH identifi ed as being from Mauritius was of questionable of A. pilatus, referring to deep-water and shallow-water forms. locality, and that the sole specimen from the Cape of Good Hope The basis for the colour differences is unclear and should be (which he identifi ed as the ʻtypeʼ of D. punctulatus) was investigated.

Thus, I conclude description contains two spellings of the specifi c name: two as that Sir A. Smith procured his specimen from a passing ship, not whitleyi and one as whiteleyi.
